Technical Field

[0001] This invention relates to the field of hardware testing technology, and in particular to a testing method for a waterproof display screen, an electronic device, and a computer-readable storage medium. Background Technology

[0002] The manufacturing process of waterproof displays is more advanced than that of ordinary displays, and the requirements for process packaging are also more stringent. Therefore, timely and effective testing of the waterproof performance of waterproof displays is of great significance.

[0003] Currently, the most common testing method for waterproof displays is a semi-automated testing method. This involves fixing the waterproof display in a frame, placing the frame, including the waterproof display, in an underwater environment for a certain period of time, and then removing the waterproof display from the underwater environment to test whether it is working properly.

[0004] While semi-automated testing methods meet the testing requirements for waterproof displays, their low level of intelligence still results in excessive time consumption during the testing process. Summary of the Invention

[0005] This invention provides a testing method and a computer-readable storage medium for waterproof displays, the main purpose of which is to improve the testing efficiency of waterproof displays.

[0006] To achieve the above objectives, the present invention provides a testing method for a waterproof display screen, comprising:

[0007] Receive a test instruction for a waterproof display screen, and determine the display screen test equipment according to the test instruction. The display screen test equipment includes a sealed chamber, a fixing frame, a power supply circuit, and a water storage tank. One side of the sealed chamber is a glass surface, and the other sides are concrete surfaces. The fixing frame, the power supply circuit, and the water storage tank are all located inside the sealed chamber. The water storage tank includes multiple water tanks, and each water tank can store water at different temperatures.

[0008] According to the test instructions, the waterproof display screen is fixed to the mounting bracket in the display screen testing equipment, and the light-emitting surface of the waterproof display screen corresponds to the glass surface of the sealed chamber;

[0009] By using an electrical circuit to power a waterproof display screen in a fixed frame, a light-emitting waterproof display screen is obtained;

[0010] After the luminous waterproof display screen has been powered on for a specified time, the glass temperature of the glass surface is measured to obtain the temperature of the glass without water flow, and the working heat value of the luminous waterproof display screen under no water flow is calculated based on the temperature of the glass without water flow.

[0011] When the heat value of the luminous waterproof display screen is less than the specified heat value when no water is flowing through it, the water temperatures of the first, second, ..., nth water tanks in the water storage compartment are sequentially set to t1, t2, ..., t... n And t1 is less than t2, ..., t n-1 Less than t n ;

[0012] Water from each storage tank is sequentially introduced into the sealed chamber until it submerges the waterproof display screen in the fixed frame. Then, the waterproof display screen is powered on, and it is determined whether the display screen is displaying normally. Multiple sets of display results are obtained, with each set of display results corresponding to the water temperature of the storage tank.

[0013] Optionally, the method of energizing the waterproof display screen in the mounting frame using an electrical circuit to obtain a light-emitting waterproof display screen includes:

[0014] After setting the voltage and current of the energizing circuit, start the energizing circuit.

[0015] The waterproof display screen in the fixed frame was powered by the power-conducting circuit, and the working voltage and current of the waterproof display screen were tested multiple times to obtain multiple sets of working voltage and current.

[0016] The stable operating value of the waterproof display screen is calculated based on multiple sets of operating voltage and operating current.

[0017] If the working stability value of the waterproof display screen is less than or equal to the working stability threshold, the waterproof display screen is determined to be a non-compliant display screen, and a test failure instruction is generated and fed back to the initiator of the test instruction.

[0018] When the operating stability value of the waterproof display screen is greater than the operating stability threshold, the waterproof display screen is determined to be a light-emitting waterproof display screen.

[0019] Optionally, calculating the operating heat value of the luminous waterproof display screen under conditions without water flow based on the temperature of the unwater-filled glass includes:

[0020] Obtain the glass temperature of the waterproof display screen when it is not powered on, and get the glass temperature when it is not powered on;

[0021] Calculate the temperature difference between the temperature of the glass without water flow and the temperature of the glass without electricity.

[0022] The working heat value of the luminous waterproof display screen when no water is flowing through it is calculated based on the temperature difference value.

[0023] Optionally, the step of specifying that the heat value of the luminous waterproof display screen is less than a specified heat value when it is not submerged in water further includes:

[0024] Determine the relationship between the working heat value of the luminous waterproof display screen when it is not exposed to water and the specified heat value;

[0025] When the heat value of the luminous waterproof display screen is greater than or equal to the specified heat value when it is not exposed to water, the waterproof display screen is determined to be a defective display screen, and the test failure instruction is generated and fed back to the initiator of the test instruction.

[0026] Optionally, the step of sequentially introducing water from each storage tank into the closed chamber includes:

[0027] Set the import power of the i-th water storage tank to import water into the closed chamber;

[0028] Water is introduced from the i-th water storage tank into the closed chamber based on the input power.

[0029] Optionally, the step of introducing water from the i-th water storage tank into the closed chamber according to the introduction power includes:

[0030] Obtain the specifications of the enclosed compartment, and the distance between the waterproof display screen in the mounting bracket and the bottom of the enclosed compartment;

[0031] Based on the specifications of the enclosed chamber and the distance between the waterproof display screen and the bottom of the enclosed chamber, the amount of water required to submerge the waterproof display screen in the mounting frame is calculated.

[0032] Water is introduced from the i-th water storage tank into the closed chamber according to the introduced power, and the introduced water volume must be greater than or equal to the flooded water volume.

[0033] Optionally, the step of introducing water from the i-th water storage tank into the closed chamber according to the introduced power includes:

[0034] The introduction time is calculated based on the introduction power and the amount of submerged water. The calculation method for the introduction time is as follows:

[0035]

[0036] Among them, T i Q represents the time it takes for the i-th water storage tank to introduce water into the closed chamber. i p represents the amount of water submerged. i This represents the volume of water introduced from the i-th water storage tank into the closed chamber per second, also known as the introduction power.

[0037] During the import time, water is imported from the i-th water storage tank into the closed chamber, and the imported water volume must be greater than or equal to the flooded water volume.

[0038] Optionally, the step of powering on the waterproof display screen includes:

[0039] Start the agitator inside the sealed chamber, which is used to agitate the water inside the sealed chamber;

[0040] Set the stirring speed of the agitator, and stir the water in the sealed chamber at the stirring speed;

[0041] Provided that the stirrer is working normally, the waterproof display screen is powered on using the power-on circuit.

[0042] Optionally, the enclosed compartment has a three-dimensional rectangular structure.

[0043] To achieve the above objectives, the present invention also provides a testing apparatus for a waterproof display screen, comprising:

[0044] The test equipment startup module is used to receive test instructions for the waterproof display screen and determine the display screen test equipment according to the test instructions. The display screen test equipment includes a closed chamber, a fixing frame, a power supply circuit, and a water storage tank. One side of the closed chamber is a glass surface, and the other sides are concrete surfaces. The fixing frame, the power supply circuit, and the water storage tank are all located inside the closed chamber. The water storage tank includes multiple water tanks, and each water tank can store water at different temperatures.

[0045] The display screen fixing module is used to fix the waterproof display screen to the fixing frame in the display screen testing equipment according to the test instructions, and the light-emitting surface of the waterproof display screen corresponds to the glass surface of the sealed chamber;

[0046] The working heat value calculation module is used to power the waterproof display screen in the fixed frame using the power circuit to obtain the luminous waterproof display screen. After the luminous waterproof display screen is powered on for a specified time, the glass temperature of the glass surface is measured to obtain the temperature of the glass without water, and the working heat value of the luminous waterproof display screen under the condition of no water is calculated based on the temperature of the glass without water.

[0047] The underwater testing module is used to sequentially set the water temperatures of the first, second, ..., nth water tanks in the water storage compartment to t1, t2, ..., t when the working heat value of the luminous waterproof display screen in the absence of water is less than a specified heat value. n And t1 is less than t2, ..., t n-1 Less than t n Water from each water storage tank is sequentially introduced into the sealed chamber until the water submerges the waterproof display screen in the fixed frame. Then, the waterproof display screen is powered on, and it is determined whether the waterproof display screen is displaying normally. Multiple sets of display results are obtained, with each set of display results corresponding to the water temperature of the water storage tank.

[0048] To address the above problems, the present invention also provides an electronic device, the electronic device comprising:

[0049] Memory, storing at least one instruction; and

[0050] The processor executes the instructions stored in the memory to implement the above-described test method for the waterproof display screen.

[0051] To address the aforementioned problems, the present invention also provides a computer-readable storage medium storing at least one instruction, which is executed by a processor in an electronic device to implement the aforementioned test method for a waterproof display screen.

[0052] To address the problems described in the background art, this invention first receives a test instruction for a waterproof display screen, and then determines a display screen testing device based on the test instruction. The display screen testing device includes a sealed chamber, a mounting frame, a power supply circuit, and a water storage tank. One side of the sealed chamber is glass, while the other sides are concrete. The mounting frame, power supply circuit, and water storage tank are all located within the sealed chamber, and the water storage tank includes multiple water tanks, each capable of storing water at different temperatures. Therefore, this invention constructs a display screen testing device for testing waterproof display screens to improve testing intelligence. The display screen testing device has a high degree of integration, consisting of a sealed chamber, a mounting frame, a power supply circuit, and a water storage tank. Further, according to the test instructions, the waterproof display screen is fixed to the mounting frame in the display screen testing equipment, with the luminescent surface of the waterproof display screen corresponding to the glass surface of the sealed chamber. Power is supplied to the waterproof display screen in the mounting frame using a power circuit to obtain a luminescent waterproof display screen. After the luminescent waterproof display screen has been powered on for a specified time, the glass temperature of the glass surface is measured to obtain the temperature of the glass without water flow. Based on the temperature of the glass without water flow, the working heat value of the luminescent waterproof display screen under no-water conditions is calculated. It can be seen that the first test procedure of this embodiment is to test whether the heat dissipation of the waterproof display screen is normal. If the heat dissipation of the waterproof display screen is abnormal, it indicates that the waterproof display screen has a quality problem. For safety reasons, underwater testing is not performed on the waterproof display screen. If the heat dissipation of the waterproof display screen is normal, the water temperatures of the first water tank, the second water tank, ..., the nth water tank in the water storage chamber are sequentially set to t1, t2, ..., t... n And t1 is less than t2, ..., t n-1 Less than t n Water from each storage tank is sequentially introduced into the sealed chamber until the waterproof display screen in the fixed frame is submerged. The waterproof display screen is then powered on, and its normal display is checked, yielding multiple sets of display results. Each set of results corresponds to the water temperature in the storage tank. Therefore, this invention achieves fully automated testing of the waterproof display screen, requiring no human intervention, significantly reducing testing time and improving testing efficiency. Thus, the purpose of the waterproof display screen testing method, electronic device, and computer-readable storage medium proposed in this invention is to improve the testing efficiency of waterproof display screens.

[0057] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0058] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0059] This application provides a testing method for a waterproof display screen. The execution entity of the testing method includes, but is not limited to, at least one of the following electronic devices that can be configured to execute the method provided in this application: a server, a terminal, etc. In other words, the testing method for the waterproof display screen can be executed by software or hardware installed on a terminal device or a server device, and the software can be a blockchain platform. The server includes, but is not limited to, a single server, a server cluster, a cloud server, or a cloud server cluster.

[0060] Reference Figure 1 The diagram shown is a flowchart illustrating a testing method for a waterproof display screen according to an embodiment of the present invention. In this embodiment, the testing method for the waterproof display screen includes:

[0061] S1. Receive the test command for the waterproof display screen, and determine the display screen test equipment according to the test command. The display screen test equipment includes a closed chamber, a fixing frame, a power supply circuit and a water storage tank. One side of the closed chamber is a glass surface and the other sides are concrete surfaces. The fixing frame, the power supply circuit and the water storage tank are all located inside the closed chamber. The water storage tank includes multiple water storage pools, and each water storage pool can store water at different temperatures.

[0062] It should be explained that the display screen testing equipment is adapted to the waterproof function of waterproof display screens. Furthermore, it should be emphasized that in this embodiment of the invention, the display screen testing equipment includes a sealed chamber, a mounting frame, an electrical circuit, and a water storage tank. (See reference...) Figure 2 The image shown is a display screen testing device according to one embodiment of the present invention.

[0063] In sequence, the enclosed chamber is the external structure of the entire display screen testing equipment. It is generally a three-dimensional rectangular structure with most sides made of concrete and only one side made of glass.

[0064] The enclosed chamber includes a mounting frame, an electrical circuit, and a water storage tank. The mounting frame and the electrical circuit are integrated together, which facilitates direct power supply and testing of the waterproof display screen.

[0065] In addition, the water storage tank includes multiple water pools, and each water pool is equipped with a heater or cooler. Through the heater or cooler, each water pool can store water at different temperatures for subsequent testing of the waterproof display screen.

[0066] S2. Fix the waterproof display screen to the mounting bracket in the display screen testing equipment according to the test instructions, and make sure that the light-emitting surface of the waterproof display screen corresponds to the glass surface of the sealed chamber;

[0067] It should be understood that the embodiments of the present invention mainly test the waterproof display screen by immersing it in water at different temperatures, thereby checking whether a series of parameters such as brightness and reflectivity change under stable power and voltage conditions. Therefore, when fixing the waterproof display screen using a mounting bracket, the light-emitting surface of the waterproof display screen needs to correspond to the glass surface of the sealed chamber, so that a series of parameter values ​​of the waterproof display screen can be tested through the glass surface.

[0068] S3. Power the waterproof display screen in the fixed frame using the power-conducting circuit to obtain a light-emitting waterproof display screen;

[0069] Specifically, the method of using an electrical circuit to energize the waterproof display screen in the mounting frame to obtain a light-emitting waterproof display screen includes:

[0070] After setting the voltage and current of the energizing circuit, start the energizing circuit.

[0071] The waterproof display screen in the fixed frame was powered by the power-conducting circuit, and the working voltage and current of the waterproof display screen were tested multiple times to obtain multiple sets of working voltage and current.

[0072] The stable operating value of the waterproof display screen is calculated based on multiple sets of operating voltage and operating current.

[0073] If the working stability value of the waterproof display screen is less than or equal to the working stability threshold, the waterproof display screen is determined to be a non-compliant display screen, and a test failure instruction is generated and fed back to the initiator of the test instruction.

[0074] When the operating stability value of the waterproof display screen is greater than the operating stability threshold, the waterproof display screen is determined to be a light-emitting waterproof display screen.

[0075] For example, assuming the power-on circuit is set to a voltage of 220V and a current of 10A before being activated, the charge in the power-on circuit can be used to excite the waterproof display screen. It should be emphasized that the first test procedure for the waterproof display screen in this embodiment of the invention is to test the voltage and current stability of the waterproof display screen. If the voltage and current stability of the waterproof display screen is poor, it indicates that before the waterproof test is performed, its internal structure, manufacturing process, or other factors have already caused instability in the working state of the waterproof display screen, thus it can be determined as a substandard display screen.

[0076] Furthermore, embodiments of the present invention may employ machine learning algorithms such as XGBoost and support vector machines, and calculate the stable operating value of the waterproof display screen using multiple sets of operating voltages and currents. Since these are already disclosed technical methods, they will not be described in detail here.

[0077] S4. After the luminous waterproof display screen has been powered on for a specified time, measure the glass temperature of the glass surface to obtain the temperature of the glass without water, and calculate the working heat value of the luminous waterproof display screen without water based on the temperature of the glass without water.

[0078] Understandably, when a luminous waterproof display screen faces a glass surface, the heat value of the screen will be transferred to the glass surface, causing the temperature of the glass surface to rise. Therefore, the working heat value of the waterproof display screen when it is powered on can be calculated from the glass temperature.

[0079] For example, if the power-on time of the luminous waterproof display screen reaches 20 minutes, and the glass temperature of the glass surface is measured to be 40 degrees, then this 40 degrees is the glass temperature when no water is flowing through it.

[0080] Specifically, the calculation of the operating heat value of the luminous waterproof display screen under conditions of no water flow based on the temperature of the unwatered glass includes:

[0081] Obtain the glass temperature of the waterproof display screen when it is not powered on, and get the glass temperature when it is not powered on;

[0082] Calculate the temperature difference between the temperature of the glass without water flow and the temperature of the glass without electricity.

[0083] The working heat value of the luminous waterproof display screen when no water is flowing through it is calculated based on the temperature difference value.

[0084] For example, if the glass temperature is 30 degrees when the power is off, the temperature difference is +10 degrees. Since the +10 degree increase comes from the heat transfer of the waterproof display after it is powered on, the working heat value of the display when it is not wet can be calculated using the temperature difference heat calculation formula. Since the temperature difference heat calculation formula is publicly available, it will not be elaborated here.

[0085] S5. When the working heat value of the luminous waterproof display screen is less than the specified heat value when no water is flowing through it, the water temperature of the first water tank, the second water tank, ..., the nth water tank in the water storage tank is sequentially set to t1, t2, ..., t... n And t1 is less than t2, ..., t n-1 Less than t n ;

[0086] Specifically, the step of specifying that the heat value of the luminous waterproof display screen is less than a specified heat value when it is not exposed to water also includes:

[0087] Determine the relationship between the working heat value of the luminous waterproof display screen when it is not exposed to water and the specified heat value;

[0088] When the heat value of the luminous waterproof display screen is greater than or equal to the specified heat value when it is not exposed to water, the waterproof display screen is determined to be a defective display screen, and the test failure instruction is generated and fed back to the initiator of the test instruction.

[0089] Understandably, if the heat value of the illuminated waterproof display screen when it is not exposed to water is greater than or equal to the specified heat value, it indicates that the heat value released by the waterproof display screen during normal operation is too high. This directly indicates that the waterproof display screen does not meet the requirements in terms of heat control technology, and the waterproof display screen can be determined to be a substandard display screen.

[0090] Furthermore, if the heat value of the luminous waterproof display screen when not in contact with water is less than the specified heat value, the next waterproof test can be performed. Therefore, the water temperatures of the first, second, ..., nth water tanks in the water storage compartment are first set as t1, t2, ..., t... n And t1 is less than t2, ..., t n-1 Less than t n .

[0091] S6. Water from each water storage tank is sequentially introduced into the closed chamber until the water submerges the waterproof display screen in the fixed frame. Then, the waterproof display screen is powered on, and it is determined whether the waterproof display screen is displaying normally. Multiple sets of display results are obtained, and each set of display results corresponds to the water temperature of the water storage tank.

[0092] The process of sequentially introducing water from each storage tank into the sealed chamber includes:

[0093] Set the import power of the i-th water storage tank to import water into the closed chamber;

[0094] Water is introduced from the i-th water storage tank into the closed chamber based on the input power.

[0095] Further, the step of introducing water from the i-th water storage tank into the closed chamber according to the introduction power includes:

[0096] Obtain the specifications of the enclosed compartment, and the distance between the waterproof display screen in the mounting bracket and the bottom of the enclosed compartment;

[0097] Based on the specifications of the enclosed chamber and the distance between the waterproof display screen and the bottom of the enclosed chamber, the amount of water required to submerge the waterproof display screen in the mounting frame is calculated.

[0098] Water is introduced from the i-th water storage tank into the closed chamber according to the introduced power, and the introduced water volume must be greater than or equal to the flooded water volume.

[0099] For example, if the enclosed compartment is three-dimensional with a bottom length of 60cm, a width of 40cm, and a height of 200cm, and the waterproof display screen in the mounting frame is 70cm away from the bottom of the enclosed compartment, then the amount of water required to submerge the waterproof display screen in the mounting frame can be calculated based on the bottom length of 60cm, width of 40cm, and height of 70cm.

[0100] Further, the step of introducing water from the i-th water storage tank into the closed chamber according to the introduced power includes:

[0101] The introduction time is calculated based on the introduction power and the amount of submerged water. The calculation method for the introduction time is as follows:

[0102]

[0103] Among them, T i Q represents the time it takes for the i-th water storage tank to introduce water into the closed chamber. i p represents the amount of water submerged. i This represents the volume of water introduced from the i-th water storage tank into the closed chamber per second, also known as the introduction power.

[0104] During the import time, water is imported from the i-th water storage tank into the closed chamber, and the imported water volume must be greater than or equal to the flooded water volume.

[0105] For example, after water at temperature t2 corresponding to the second water storage tank is introduced into the sealed chamber, it is necessary to test whether the waterproof display screen displays abnormally when the water temperature is t2. Therefore, in detail, the step of powering on the waterproof display screen includes:

[0106] Start the agitator inside the sealed chamber, which is used to agitate the water inside the sealed chamber;

[0107] Set the stirring speed of the agitator, and stir the water in the sealed chamber at the stirring speed;

[0108] Provided that the stirrer is working normally, the waterproof display screen is powered on using the power-on circuit.

[0109] It should be explained that the stirrer is used to increase the harshness of the testing environment, thereby raising the testing requirements for the waterproof display screen. And as one can imagine, each set of underwater tests at different temperatures will yield test results indicating whether the waterproof display screen displays correctly; for example, t1 corresponds to one set of display results, t2 corresponds to another set of display results, ..., t... n The corresponding set of results will be displayed.

[0110] To address the problems described in the background art, this invention first receives a test instruction for a waterproof display screen, and then determines a display screen testing device based on the test instruction. The display screen testing device includes a sealed chamber, a mounting frame, a power supply circuit, and a water storage tank. One side of the sealed chamber is glass, while the other sides are concrete. The mounting frame, power supply circuit, and water storage tank are all located within the sealed chamber, and the water storage tank includes multiple water tanks, each capable of storing water at different temperatures. Therefore, this invention constructs a display screen testing device for testing waterproof display screens to improve testing intelligence. The display screen testing device has a high degree of integration, consisting of a sealed chamber, a mounting frame, a power supply circuit, and a water storage tank. Further, according to the test instructions, the waterproof display screen is fixed to the mounting frame in the display screen testing equipment, with the luminescent surface of the waterproof display screen corresponding to the glass surface of the sealed chamber. Power is supplied to the waterproof display screen in the mounting frame using a power circuit to obtain a luminescent waterproof display screen. After the luminescent waterproof display screen has been powered on for a specified time, the glass temperature of the glass surface is measured to obtain the temperature of the glass without water flow. Based on the temperature of the glass without water flow, the working heat value of the luminescent waterproof display screen under no-water conditions is calculated. It can be seen that the first test procedure of this embodiment is to test whether the heat dissipation of the waterproof display screen is normal. If the heat dissipation of the waterproof display screen is abnormal, it indicates that the waterproof display screen has a quality problem. For safety reasons, underwater testing is not performed on the waterproof display screen. If the heat dissipation of the waterproof display screen is normal, the water temperatures of the first water tank, the second water tank, ..., the nth water tank in the water storage chamber are sequentially set to t1, t2, ..., t... n And t1 is less than t2, ..., t n-1 Less than t n Water from each storage tank is sequentially introduced into the sealed chamber until the waterproof display screen in the fixed frame is submerged. The waterproof display screen is then powered on, and its normal display is checked, yielding multiple sets of display results. Each set of results corresponds to the water temperature in the storage tank. Therefore, this invention achieves fully automated testing of the waterproof display screen, requiring no human intervention, significantly reducing testing time and improving testing efficiency. Thus, the purpose of the waterproof display screen testing method, electronic device, and computer-readable storage medium proposed in this invention is to improve the testing efficiency of waterproof display screens.

[0111] like Figure 3 The diagram shown is a functional block diagram of a waterproof display screen testing device provided in an embodiment of the present invention.

[0112] The waterproof display screen testing device 100 of the present invention can be installed in an electronic device. Depending on the functions implemented, the waterproof display screen testing device 100 may include a testing equipment startup module 101, a display screen fixing module 102, a working heat value calculation module 103, and an underwater testing module 104. The module described in this invention can also be called a unit, referring to a series of computer program segments that can be executed by the processor of an electronic device and can perform a fixed function, stored in the memory of the electronic device.

[0113] The test equipment start module 101 is used to receive the test command of the waterproof display screen and determine the display screen test equipment according to the test command. The display screen test equipment includes a closed chamber, a fixed frame, a power circuit and a water storage tank. One side of the closed chamber is a glass surface and the other sides are concrete surfaces. The fixed frame, the power circuit and the water storage tank are all located inside the closed chamber. The water storage tank includes multiple water tanks, and each water tank can store water at different temperatures.

[0114] The display screen fixing module 102 is used to fix the waterproof display screen to the fixing frame in the display screen testing equipment according to the test command, and the light-emitting surface of the waterproof display screen corresponds to the glass surface of the sealed chamber.

[0115] The working heat value calculation module 103 is used to power the waterproof display screen in the fixed frame using the power circuit to obtain the luminous waterproof display screen. After the luminous waterproof display screen is powered on for a specified time, the glass temperature of the glass surface is measured to obtain the temperature of the glass without water, and the working heat value of the luminous waterproof display screen under the condition of no water is calculated based on the temperature of the glass without water.

[0116] The underwater testing module 104 is used to sequentially set the water temperatures of the first, second, ..., nth water tanks in the water storage tank to t1, t2, ..., t3 when the working heat value of the luminous waterproof display screen in the absence of water is less than a specified heat value. n And t1 is less than t2, ..., t n-1 Less than t n Water from each water storage tank is sequentially introduced into the sealed chamber until the water submerges the waterproof display screen in the fixed frame. Then, the waterproof display screen is powered on, and it is determined whether the waterproof display screen is displaying normally. Multiple sets of display results are obtained, with each set of display results corresponding to the water temperature of the water storage tank.

[0117] In detail, the modules in the waterproof display screen testing device 100 described in this embodiment of the invention employ the same methods as described above during use. Figure 1 The blockchain-based product supply chain management method described herein uses the same technical means and can produce the same technical effects, so it will not be elaborated here.

[0118] like Figure 4 The diagram shown is a structural schematic of an electronic device that implements a testing method for a waterproof display screen according to an embodiment of the present invention.

[0119] The electronic device 1 may include a processor 10, a memory 11 and a bus 12, and may also include a computer program stored in the memory 11 and executable on the processor 10, such as a test method program for a waterproof display screen.
